Filed: 1962-03-01
Abstract: 961,356. Automatic feed weighers. PORTASILO Ltd. May 31,1963 [March 1,1962], No. 8016/62: Heading G1W. Measuring and delivering apparatus of the kind having a beam 1 mounted for pivotal movement about an axis transverse to its length e.g. in bearings 3, and along which a container 5 is movable between a material-receiving position, shown in Fig. 3, and a delivery position, is arranged such that when the container 5 is moved to its materialreceiving position, a vale member 10 is automatically moved to an open position when it is held by retaining means 19, whereby material is fed from a hopper 4 into the container 5, and after a predetermined weight has been so fed, the weight of the material causes pivoting of the beam so releasing the retaining means by a relative rolling motion between the means 19 and the part i.e. a cross-bar 12, associated with the valve member which engages with the retaining means, so that the valve member 10 is automatically returned to its closed position. The beam 1 is in the form of two opposed channel members 2 in which rollers 7 on the container 5 are engaged a handle 8 being provided for manual movement of the container. The valve member 10 is in the form of a flat plate guided by a guide 11 and a fixed rod 13 which passes through the crossbar 12, this beam being secured to the valve member 10. The valve member is held closed by springs 15 against rubber stops 18. The retaining means 19 is pivotably mounted on an arm 20 itself pivotally mounted on a fixed member 21. The cross-bar 12 has an inclined plate 29 welded to it to engage with a flat 28 on a cam surface 22 on the means 19, which means also comprises a finger 23 which is attracted to and held by a magnet 26 on a stirrup 24 carried by the beam 1. A coil spring 27 is provided to ensure contact of the finger 23 with the magnet. In operation the container 5 is pushed from its delivery position at the left hand end of the beam 1 in the drawings (not shown). When a cross-beam 9 on the container 5 contacts depending lugs 16 on the cross-bar 12, (see Fig. 1) the crossbar 12 is pushed to the left in the drawings to open the valve member 10. Eventually the position shown in full lines in Fig. 3 is reached where the retaining means 19 is latched behind the cross-bar 12 to hold the valve member 10 open. When the weight of the material in the container 5 is sufficient to pivot the beam 1 against the action of a fixed or sliding counterweight carried at the right hand end of the beam 1 (not shown), the parts move to the dotted line positions shown in Fig. 3 and the cam surface 22 rolls over the cross-bar 12 to release the valve member which is then automatically closed.

Filed: 1926-03-24
Abstract: 251,246. France, A. April 23, 1925. [Convention date]. Upward current classifiers. -A process of washing coal and other minerals containing a rela. tively small proportion of heavy constituents consists in introducing into the conveying stream simultaneously with the material to be treated a quantity of appropriately sized heavy material which becomes associated with the heavy constituents and is withdrawn therewith and subsequently separated therefrom for re-use. In the case of coal, the heavy material added may be some of the slaty constituents previously separated from the coal. In the plant shown, quartz or felspar granules are fed to the end b of a trough a from which separators c, d depend and to which the material to be treated is supplied from a hopper h. The heavy constituents together with the felspar &c. are discharged on to a screen i of such mesh that the felspar &c. is separated and passes to a vessel n for re-use. The intermediate constituents are withdrawn through the separators d and a slot e and may be returned to the trough a by an elevator g for rewashing, the lightest constituents being discharged at the lower end of the trough. In a modification, heavy constituents withdrawn by the first separator are passed through a shoot provided with adjustable means whereby a portion of them may be supplied to the upper end of the trough.

Title: Modified Phenol Formaldehyde Resins
IPC: C08G8/24
Filed: 1967-02-21
Abstract: 1,177,802. Phenolic resins. WEYERHAEUSER CO. 21 Feb., 1967 [25 Feb., 1966], No. 8163/67. Heading C3R. A phenolic resin is prepared by reacting phenol (1 mol.) with formaldehyde (0À55-1À2 mols.) in the presence of an ortho-directing catalyst and reacting the product with a polyhydric phenol. Both phenol and formaldehyde may contain water. The formaldehyde may be present as paraformaldehyde. The catalyst may be the acetate of magnesium, calcium, strontium, barium, zinc or cadmium. In the first stage the reactants are heated under reflux (96-98‹ C.) until a product having a viscosity of about 125 centipoises, a solids content up to 65% and a pH of about 6 is obtained. Reflux is then stopped so that the polyhydric phenol may be added. This may be either resorcinol (0À2-0À8 mols.) or a reaction product of a chlorophenol and an alkali metal hydroxide. Then an alkali metal hydroxide, e.g. NaOH, water and an alcohol, e.g. ethanol or ethylene glycol, may be added to stabilize, catalyse and wet the resin and reduce its solids content. The second stage reaction is also under reflux and may be under superatmospheric pressure. The product of this stage may have a viscosity between 400 and 2000 centipoises. It may be cured by mixing with 20-100% of a hardener comprising water, methanol, formalin or aqueous paraformaldehyde solution, a filler, hydroxy-ethyl cellulose as a protective colloid, pyrogenic silica and a wetting agent. The filler may be aluminosilicate clay, walnut shell flour or crystalline silica flour. The viscosity of the resin hardener mixture may be 600-8000.

Bore-hole apparatus.-An earth - boring machine actuated by electric motors enclosed therein comprises three independent connected sections, the upper one J, Fig. 1, enclosing the suspension and anchoring means, the intermediate one K, Figs. 1 and 3, containing the motors and speedreducing gear, and the lower one L, Figs. 3 and 6, containing the boring-bit. The sections are connected by bolts &c. 22, 44. The anchoring-means comprises blades 16 connected by links 15 to a fixed spider 14 and by further links 17 to a collar 18 on a spring-pressed rod 10 connected to the suspension means 7; on the machine reaching the bottom of the bore-hole, expansion of the spring 13 forces the blades 16 through slots in the casing 1 to engage the surrounding earth. The electric conductors are connected to a closure 3 which is rotatable on the casing 1 and carries spring contacts 5 engaging contact rings 6. The electric motors are arranged in independent chambers M and their co-axial shafts 26, 26<1>, 26<11> are connected to drive a shaft 30 carrying pinions 29, 36 of different diameters; these pinions engage pinions 31, 35 mounted on common shafts 33 carried by a rotatable spider 32 and the pinions 31 engage a fixed internallytoothed wheel 28 and so cause the pinions 35 to rotate an internally-toothed wheel 37, and a shaft 41 carried thereby, at reduced speed. The shaft 41 has a square end 52 which rotates a tube 51 which is slidable thereon and carries the bit 58. A non-rotating nut 49 connected to the tube 51 engages a threaded part 48 of the shaft 41 to advance or withdraw the bit. The bit is of helical form and enclosed in a cylinder 59 rotating with the bit; the cylinder 59 and outer case 47 have doors for removal of the debris. At the end of either the advance or withdrawal of the bit, the motors are automatically stopped by the nut 49 contacting with stops and so exerting a pull on a cord enclosed in a tube 69, Fig. 9; the cord pulls down a rod 70 against the action of a spring 72, which rod, through engaging projections 73, 74, moves a rod 76 against the resistance of a spring 80 and so causes a crank 78 to open the switch; on depressing a button 85, a bell-crank lever 81 overcomes a spring 74' and disengages the projections 73, 74, the spring 80 then returning the rod 76 and re-closing the switch.
